A) The lens in Fig. b is a converging lens.

B) An object placed to the left of f in Fig. b results in an image on the right side of the lens.

C) An object placed between f and the lens in Fig. b produces a virtual image.

D) An object placed betweeen f and the lens in Fig. b results in an image on the left side of the lens.

E) An object placed to the left of f in Fig. b produces a real image.

Answer 1

In optics, the covex lens is called coverging lens and concavelence is called divergent lens

In the given Fig.a. is convex lence in Fig.b., the lens is concave

A) The lens in Fig. b is a converging lens   (F)

B) An object placed to the left of f in Fig. b results in an image on the right side of the lens (F)

      Because in concave lens the image formed in same side of object

C) An object placed between f and the lens in Fig. b produces a virtual image. (T)

        beacuse concavelence always produced virtual image

D) An object placed betweeen f and the lens in Fig. b results in an image on the left side of the lens (T)

Because in concave lens the image formed in same side of object

E) An object placed to the left of f in Fig. b produces a real image.(F)

Fig. b is concave lens and produce only virtual image
